Bootstrap 5 Migrate Tool

A command-line script designed to help you upgrade your Bootstrap 4 projects to Bootstrap 5. It uses gulp with gulp-replace to replace class names within your folder of HTML pages/templates.

Features

• Replaces all the Bootstrap 4 class names with the renamed Bootstrap 5 class names
• Replaces deprecated components (such as .jumbotron and .media) with utility classes
• Renames all the data attributes (such as data-toggle and data-target) to the new names
• Updates all Bootstrap v4 CDN links (cloudflare, jsdelivr, stackpath.bootstrapcdn.com and unpkg) to latest version of Bootstrap v5
• Options to overwrite the existing files in place or save the migrated files to a different folder
• Can convert not only HTML files but also ASP, CSHTML, EJS, ERB, HBS, JSP, PHP, VUE, and other template files
• Provides a summary of the changes made

Usage

Clone this repo and then run the following command:

npm install

Copy your HTML templates to the src folder.

Then run the following command to start the migration:

npx gulp migrate

The migrated HTML templates will overwrite the files in place by default. If you want to keep the original files, you can use the --dest flag to specify a destination folder. See the Options section for more details.

Options

Options that may be set via CLI flags. For example: npx gulp migrate --src "./src-dir" --overwrite --verbose

• src: './src' - string that will be passed to the gulp {@link src} function
• dest: ./- string that will be passed to the gulp {@link dest} function
• overwrite: true - overwrite the existing files in place. Cannot be used with --dest flag
• verbose: true- print the path of each generated / modified file to the console
• defaultFileGlob: '**/*.{asp,aspx,cshtml,ejs,erb,hbs,html,htm,jsp,php,twig,vue}' - default glob for files to search in. Default: Search all folder and files recursively
